An autopsy case of right‐sided infective endocarditis combined with mitral valvular involvement in a 20‐year‐old male Japanese with ventricular septal defect (VSD) was reported. The vegetations were found on the endocardium bordering VSD, tricuspid valve, mural endocardium of the right ventricular outflow tract, and even the pulmonic valve, resulting in forming infective aneurysm of the pulmonary trunk. Streptococcus was morphologically identified in the vegetations obtained at autopsy. On the other hand, smaller vegetations were also noted on the mitral valve. The mechanisms of the mitral extending were discussed when right‐sided infective endocarditis associated with VSD preceded that on the mitral valve. The authors think that mitral regurgitation in relation to VSD and right to left shunt through VSD which occur even temporarily may be the most important mechanism responsible for the mitral valvular involvement. Several differences between right‐sided and left‐sided infective endocarditis were also reviewed. ACTA PATHOL. JPN. 35 : 459–471, 1985
